Blocks to convert between latitude, longitude, altitude and Earth-centered

inertial coordinates

The LLA to ECI Position block in the Utilities/Axes Transformations sublibrary converts

geodetic latitude, longitude, altitude (LLA) coordinates to Earth-centered inertial (ECI)

position coordinates, based on the specified reduction method and Universal Coordinated

Time (UTC), for the specified time and geophysical data.

The ECI Position to LLA block converts Earth-centered inertial (ECI) position

coordinates to geodetic latitude, longitude, altitude (LLA) coordinates, based on the

specified reduction method and Universal Coordinated Time (UTC), for the specified time

and geophysical data.
